Single-Switch Voltage-Doubler Rectifier Derived from Half-Bridge Configuration

Abstract

A novel switch-mode voltage-doubler rectifier derived from the half-bridge configuration using diodes is studied. This has an advantage that an only power switching device can provide the necessary control over the current. The arrangement tested, using an insulated-gate bipolar transistor and a controller for output voltage, is implemented to investigate the input current waveshaping. The experimental results confirm that the input current can be waveshaped sinusoidally with a near-unity power factor under the output voltage duplication.
